Both随机方法(请说明由何人用什么方法产生随机序列):
本研究采用随机、平行对照设计,将符合入选资格并签署知情同意书的受试者按照 1:1:1 的比例随机分配至 3 个治疗组。本研究采用中央随机化系统对受试者进行随机分组,随机化方法为“动态随机”,无分层因素。在随机入组受试者过程中,优先保证两个分组的受试者数量平衡。在此前提下,尽量保证每个试验机构中的两个分组的受试者数量平衡。研究者或合格的指定人员通过各自的密码进入交互式应答系统(IWRS),分配给受试者随机号,同时也通过 IWRS 获得受试者相应的需接受的研究药物编号Randomization Procedure (please state who
generates the
random number sequence and by what method):
This study adopted a randomized, parallel controlled design. Subjects who met the inclusion criteria and signed the informed consent form were randomly assigned to three treatment groups in a ratio of 1:1:1. In this study, the subjects were randomly grouped using a central randomization system. The randomization method was "dynamic randomization", with no stratification factors. During the process of randomly enrolling subjects, priority should be given to ensuring a balanced number of subjects in the two groups. Under this premise, efforts should be made to ensure that the number of subjects in the two groups of each experimental institution is balanced as much as possible. Researchers or qualified designated personnel enter the Interactive Response System (IWRS) through their respective passwords, assign random numbers to the subjects, and also obtain the corresponding drug numbers that the subjects need to receive through IWRS是否公开试验完成后的统计结果:
